  • I have Opera 22 installed as a portable version on a USB key, running on a MAC that is a work computer (not my personal computer). I was not able to open pdf files in Opera when the "Adobe Acrobat NPAPI Plug-in, Version 10.1.3" was enabled. However if I disable the plugin, I am given the option to download the pdf. Once downloaded, I am able to open the pdf with Adobe Reader installed on the work computer.

    Not sure if I can install a different plugin that would work, but at least the method of disabling the NPAPI plugin is a workaround to open pdf's from a website.

    FYI: Type opera:plugins in the address bar of Opera to see your installed plugins, and to disable or enable them.

  • You could also install this extension, probably.

  • I'll give it a try when I get more bandwidth available to download at another location.

    FTR, here is the english link to the above:
